STEAM AND AIR ENGINE.

SPECIFICATION forming part of Letters Patent No. 89,148, dated January3, 1893.

Application filed March 24, 1892- Serial No. 426,262- (No model.

Be it known that we, JACOB HAUSER, a citizen of the Republic ofSwitzerland, and JOHN WHITTAKER, a citizen of the United States, bothresiding at Boston, in the county of Suffolk and State of Massachusetts,have invented new and useful Improvements in Steam and Air Engines, ofwhich the following is a specification.

This invention relates to engines in which both steam and air areemployed simultaneously, and it consists in the construction andauxiliary to the cylinder of the engine which.

transmits the power.

In the accompanying drawings, in which similar letters of referenceindicate like parts;

Figure 1 is an elevation illustrating our invention. Fig. 2 is alongitudinal vertical section of the compressor-cylinder.

A represents a driving mechanism or engine placed upon a suitable bed a,and B is the compressor-cylinder set upon the same bed, the Wholeconstituting a compressor. The outer shell of this cylinder (see Fig. 2)is lettered B and is provided with the air-inlet C, the water inductionpipe D provided with the check-valve D, and the outlet E for both waterand air. Within the outer shell is an inner shell. or cylinder Fprovided with the inlet-valves d and g on opposite sides of the piston,and outlet-valves b and e placed on opposite sides of the piston. h isthe pistonrod which is driven by theengine A and pro-.

vided with the piston h within the cylinder F. As the piston is vibratedthe water and air enter the cylinder-B and pass down by means of thespace between the two cylinders and enter the cylinder F through thevalves dand g alternately, the water being con-' ducted downward by thepartition is. Thence the piston forces the mixed water and air out ofthe cylinder F through the valves 12 and e alternately into the upperportion of the space between the cylinders and out through the port E.Thence the water and air are conducted through the'pipe -1 into thereceiver I, thence through the pipe J into the heater L, and thence theexpanded a r and steam are conducted through the pipe N, provided withthe box N for catching the condensed drippings, into the auxiliarycylinder P provided with an ordinary exhaust P. This cylinder isconnected by a pistonrod R with the cylinder S connected with the engineT which transmits the power. The pipe S leads from the cylinder S to theboiler. As will readily be understood, while the wa ter is beingconverted into steam during its passage from the receiver to theauxiliar cylinder, the air is being quickly expand by heat, and, bymeans of the piston-rod It, acts as a powerful auxiliary to the steam inrunning the engine.

Havingthus fully described our invention what we claim and desire tosecure by Letters Patent is;

In a device of the character described, the combination of the followingelements, v1z., the com pressor-cylinder consisting essentially of theouter shell B provided with the water induction pipe D, air inductionopening 0 and outlet E for discharging both water and air, and the innershell F provided with the inlet-valves d g and outlet-valves b e, saidinner shell being adapted to receive a piston, as h, and being connectedwith the outer shell by the partition is; a receiver, as I, connected
